Using UxD artefacts to support the writing of user stories

User stories are recognised as valuable artefacts to agile teams. Usually, user stories are written based on functional aspects of software, leaving aside non-functional aspects. In contrast, User eXperience Design (UxD) artefacts provide information about users' needs, tasks, and context of use. We carried out an empirical study with 18 agile Brazilian agile developers that produced 42 user stories. Our results showed the artefacts most selected and revealed the reasons that led the developers to use specific UxD artefacts to support the writing of user stories. Our study brings up the discussion on how agile developers can get the support of UxD artefacts with the aim of specifying user experience requirements.
